still have lower pain Is there any chance for pregnancy?

Hi,
Welcome to ehealthforum.
If you have taken the emergency contraceptive within 24-48 hours of unprotected intercourse, it should help in preventing pregnancy. The bleeding that you experienced could be the withdrawal bleeding that usually occurs within 7-10 days of taking emergency contraception. Since these pills contain high dosages of hormones, these can affect your normal hormonal pattern and cause period abnormalities. Wait and watch for your next periods which can get delayed. If pregnancy is suspected, look out for development of symptoms suggestive of early pregnancy and visit your doctor/gynecologist for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately).
If pregnancy gets ruled out, and if you are not ready for pregnancy, but intend to remain sexually active, you should consider visiting your gynecologist to get started on suitable regular birth control measures to be protected (after your periods). Be regular with birth control use as instructed. Avoid having unprotected sexual contact. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle.
Take care.
